10271-5 The "must-have" performance guide for every HP-UX administrator and developer! HP-UX Tuning and Performance is the first book to take the guesswork out of maximizing HP-UX performance! This book introduces a comprehensive, systematic performance management methodology that addresses every stage in the lifecycle of an HP-UX system. Two of Hewlett-Packard's leading HP-UX performance experts present specific metrics, symptoms, and solutions for each key element of an HP-UX system, including hardware, the OS platform, and application development. Coverage includes: *Identifying and addressing bottlenecks: CPU, memory, disk, network, and beyond. *Key tradeoffs impacting performance in both uniprocessor and SMP environments *Choosing the right performance metrics-and using them correctly *Compiler optimization and application profiling *Designing applications for maximum performance HP-UX Tuning and Performance introduces the best generic UNIX and HP-UX specific tools for performance management and demonstrates practical ways to instrument HP-UX systems so that your measurements truly represent real-world performance.Whether you're an HP-UX sys admin, net admin, developer, or capacity planner, it's your complete guide to getting all the performance you paid for!
